These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Night Shift
Nausea Fuel: In "Gray Matter", we have the charming tale of a man who is transformed into a fungoid blob caused by a bit of gray slimy guck-infesting one of his nightly cans of beer. Later, we hear his son's story of seeing what's become of his father eating the bloated, putrefying, maggot-ridden corpse of a cat.
In "The Lawnmower Man", the title character's self-driving machine runs over a mole (an analogue of an earlier scene where the same thing happens to a cat, albeit with a different mower). The man, following close behind, eats the body of the mole just as he has been eating the expelled grass clippings.
"The Mangler" — imagining a person crushed and folded by an industrial laundry's steam ironer (and having their remains taken out in a basket) is enough to make someone ill.
Squick: Several of the stories, but especially "The Lawnmower Man".
Tear Jerker: "The Last Rung on the Ladder", and "The Woman in the Room".
